CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/844,833, filed Jul. 10, 2013, entitled “Electronic Device with a Reduced Friction Surface,” the entirety of which is incorporated herein by reference as if fully disclosed herein.

TECHNICAL FIELD

The present invention relates to electronic devices, and more particularly to an electronic device with one or more reduced friction surfaces.

BACKGROUND

Users interact with electronic devices, such as laptops, tablet computing devices, and smart telephones in a variety of ways. A user can view images on a display or input information using a touchscreen, keyboard, or buttons. The surfaces of the components in an electronic device, as well as the surface of the electronic device itself, can enhance the user experience by providing a tactile reduced friction surface that has a desired look or feel. However, mass manufacturing of the components that include the reduced friction surface can be difficult due to the presence of a cosmetic surface and/or display elements, such as symbols or glyphs. For example, machining around the full perimeter of a component may not be feasible when performed at mass manufacturing quantities. Additionally, positioning the transition between the surface of the component and the edges of the reduced friction surface in a non-visible location can be challenging depending on the design of the component. The transition can produce a noticeable and undesirable color change. The transition may also be detected by a user when the user touches or slides a finger over the surface.

SUMMARY

In one aspect, a surface of an electronic device includes a reduced friction surface comprising a glass beaded film. The reduced friction surface is disposed over at least one surface of the electronic device or of a component. The reduced friction surface includes glass beads embedded or bonded in a polymer layer. A thermoplastic elastomer layer can be under the polymer layer. A portion of the glass beads protrude from the surface of the polymer layer and provide a hardness to the glass beaded film. The polymer layer provides a flexibility or elasticity to the glass beaded film.

In another aspect, a method for producing the reduced friction surface over one or more surfaces of an electronic device includes providing a conformal glass beaded film and pressing the at least one surface into the conformal glass beaded film to dispose the glass beaded film over the at least one surface. In one embodiment, the glass beaded film is heated to a temperature that is greater than its forming temperature, which causes the glass beaded film to be pliable and conformal when formed over the at least one surface.

In another aspect, a method for producing the reduced friction surface on one or more surfaces of an electronic device includes providing a mold of the at least one surface, where the mold is made of the glass beaded film, and filling the mold with a material that becomes the at least one surface. For example, an insert molding process can be performed to inject the surface material into the glass beaded film mold.

In yet another aspect, a method for producing the reduced friction surface on one or more surfaces of an electronic device includes positioning the electronic device in a lower mold, positioning a glass beaded film over the lower mold, and heating the glass beaded film, the component and the glass beaded film, or the electronic device and the glass beaded film. An upper mold is then positioned over the lower mold and a pressure difference is created between the upper and lower molds to overlay the glass beaded film on the at least one surface of the electronic device.

In another aspect, a method for producing the reduced friction surface on one or more surfaces of an electronic device includes adhering the glass beaded film to the at least one surface and removing the polymer layer. The glass beaded film can be affixed to the at least one surface with an adhesive layer that is disposed over the portions of the glass beads protruding from the polymer layer. The glass beaded film can be heated prior to removing the polymer layer.

And in yet another aspect, a keyboard includes at least one key mechanism having a keycap and a glass beaded film disposed over the top surface of the keycap. The glass beaded film may also be disposed over at least a portion of the sides of the keycap. The glass beaded film includes glass beads disposed in a layer such that a portion of the glass beads protrude from a surface of the layer. The layer can be a polymer layer or an adhesive layer.

DETAILED DESCRIPTION

Embodiments described herein can provide a reduced friction surface for one or more surfaces of an electronic device or for one or more components in an electronic device. The surface can include the enclosure of an electronic device, a button, one or more keycaps in a keyboard, and other types of input devices. The reduced friction surface includes a glass beaded film that positions or affixes glass or glass-like beads in a polymer or resin layer. The glass or glass-like beads can protrude from the surface of the polymer layer. The glass or glass-like beads provide a hardness to the reduced friction surface while the polymer layer provides a flexibility or elasticity to the reduced friction surface. The reduced friction surface may have an increased abrasion resistance as compared to other surfaces. Additionally, the reduced friction surface may provide an improved user experienced with the electronic device as the tactile feel of the reduced friction surface may be preferred as compared to other surfaces. Moreover, the reduced friction surface may also provide an improved cosmetic appearance for the electronic device.

In some embodiments, the reduced friction surface is applied to one or more surfaces to avoid the need to position a transition between the reduced friction surface and the surface of the electronic device in a blind or non-visible area. For example, the reduced friction surface overlies a top surface and all four sides of a keycap when the reduced friction surface is applied to one or more keycaps of a keyboard. Various methods are described herein that can be used to dispose the glass beaded film to one or more surfaces of an electronic device.

Referring now to FIG. 1, there is shown a front perspective view of an example electronic device that can include one or more reduced friction surfaces. As shown in FIG. 1, the electronic device 102 can be a laptop or netbook computer that includes a display 104, a keyboard 106, and an input device 108, shown in the illustrated embodiment as a trackpad. An enclosure 110 can form an outer surface or partial outer surface and protective case for the internal components of the electronic device 102, and may at least partially surround the display 104, the keyboard 106, and the trackpad 108. The enclosure 110 can be formed of one or more components operably connected together, such as a front piece and a back piece.

The display is configured to display a visual output for the electronic device 102. The display 104 can be implemented with any suitable display, including, but not limited to, a liquid crystal display (LCD), an organic light-emitting display (OLED), or organic electro-luminescence (OEL) display.

The keyboard 106 includes multiple keys or key mechanisms that a user can use to interact with an application running on the electronic device 102. Example applications include a game, a word processing application, and a spreadsheet application. The key mechanisms can be configured in any arrangement, such as a QWERTY keyboard, and can include additional key mechanisms that provide control or operational inputs such as home, ESC, ALT, page up, page down, and function keys.

The trackpad 108 can be used to interact with one or more viewable objects on the display 104. For example, the trackpad 108 can be used to move a cursor or to select a file or program (represented by an icon) shown on the display. The trackpad 108 can use any known touch sensing technologies, including capacitive, resistive, ultrasonic, and piezoelectric touch sensing technologies.

In some embodiments, one or more surfaces of some or all of the keys in the keyboard can include a reduced friction surface. Additionally or alternatively, at least a portion of the exterior surface of the enclosure can include a reduced friction surface. The reduced friction surface will be described in more detail in conjunction with FIG. 5.

FIG. 2 is a front view of another example electronic device that can include one or more reduced friction surfaces. In the illustrated embodiment, the electronic device 200 is a smart telephone that includes an enclosure 202 surrounding a display 204 and one or more buttons 206 or input devices. The enclosure 202 can be similar to the enclosure described in conjunction with FIG. 1, but may vary in form factor and function.

The display 204 can be implemented with any suitable display, including, but not limited to, a multi-touch capacitive sensing touchscreen that uses liquid crystal display (LCD) technology, organic light-emitting display (OLED) technology, or organic electro luminescence (OEL) technology. Touch sensing technologies other than capacitive can be used in other embodiments.

The button 206 can take the form of a home button, which may be a mechanical button, a soft button (e.g., a button that does not physically move but still accepts inputs), an icon or image on a display, and so on. Further, in some embodiments, the button 206 can be integrated as part of a cover glass of the electronic device.

Like the embodiment shown in FIG. 1, at least a portion of the exterior surface of the enclosure 202 can include a reduced friction surface. Additionally or alternatively, the surface of one or more buttons, such as button 206, can include a reduced friction surface.

A keycap is the component of a key or key mechanism in a keyboard that a user touches or presses when interacting with the keyboard. Example keycaps are used to describe the reduced friction surface and techniques for producing the reduced friction surface on the keycap. However, as described earlier, the reduced friction surface and fabrication techniques can be used on other types of electronic devices or components of an electronic device. As one example, the reduced friction surface can be included on at least a portion of an enclosure or on a button. The term “electronic device” as used herein is meant to be generic and encompass an electronic device and components in, connected to (wirelessly or wired), or operable with an electronic device.

Referring now to FIG. 3, there is shown one example of a key mechanism of a keyboard. The key mechanism 300 includes a keycap 302 that is attached to a base plate 304 via a scissor mechanism 306. The base plate 304 can be a printed circuit board, a flexible circuit, or a structural member of a keyboard. The scissor mechanism 306 includes two pieces that interlock in a “scissor”-like manner, as shown in FIG. 3. The scissor mechanism 306 is typically formed out of a rigid material, such as a plastic, metal, or composite material, and provides mechanical stability to the key mechanism 300.

A deformable structure 308 along with the scissor mechanism 306 support the keycap 302. In the illustrated embodiment, the deformable structure 308 is an elastomeric dome, such as a rubber dome. When the keycap 302 is pressed down by a user in the direction of arrow 310, the keycap contacts the deformable structure 308, which in turn causes the deformable structure 308 to compress or collapse. When the deformable structure 308 compresses or collapses, the deformable structure 308 contacts a membrane 312, which activates a switch and provides an input to the electronic device.

Other embodiments can construct a key mechanism differently. By way of example only, a key mechanism can include a stacked metal and elastomeric dome, with a keycap positioned over the stacked elastomeric and metal dome. When a user depresses the keycap, the elastomeric dome depresses the metal dome to activate the switch. One example of this type of key mechanism is disclosed in United States Patent Application Publication 2011/0203912.

At least one surface of the keycap can include a reduced friction surface. For example, the reduced friction surface can be disposed over the top surface of the keycap. Alternatively, the reduced friction surface can be formed over the top and at least a portion of the four sides of the keycap. FIG. 4 illustrates one example of a keycap that includes a reduced friction surface. For clarity, the reduced friction surface 400 is shown detached from the keycap 402. The reduced friction surface 400 is disposed over and affixed to the top surface 404 of the keycap 402 and some or all of the sides 406 of the keycap 402. The amount of reduced friction surface 400 used over the sides 406 can depend on how much of the sides is visible to a user. In some embodiments, the reduced friction surface 400 completely covers all four sides of the keycap.

FIGS. 5-7 depict cross-section views of example reduced friction surface materials taken along line 5,6,7-5,6,7 in FIG. 4. In the embodiment shown in FIG. 5, the reduced friction surface includes a glass beaded film 500. As used herein, the phrases “glass beads” and “glass beaded” are meant to be generic and encompass glass and glass-like beads. The glass beaded film 500 can be a clear or light transmissive film. The glass beaded film 500 includes glass beads 502 disposed in a resin or polymer layer 504. In one embodiment, the polymer is polyurethane or PU composite and the glass beads are borosilicate beads. The glass beads 502 provide a surface that a user touches with one or more fingers when touching or interacting with a key mechanism of a keyboard.

The polymer layer 504 can be formed over a thermoplastic elastomer (TPE) layer 506. Any suitable thermoplastic elastomer material can be used, including, but not limited to a polycarbonate (PC), a PET or PETG, and an amorphous PA. An adhesive layer 508 can be disposed under the elastomeric layer 506. The adhesive layer 508 can be used to attach or affix the glass beaded film 500 to a surface.

The glass beads 502 in the glass beaded film 500 can be embedded or bonded at any depth within the polymer layer 504. For example, the glass beads 502 in FIG. 5 have a low bead sink, meaning the glass beads 502 are positioned at a lower depth in the polymer layer 504 so that a greater portion of the glass beads 502 protrude from the polymer layer 504. In the illustrated embodiment, the glass beads 502 project out a distance d1 from the surface of the polymer layer 504. When positioned at a lower depth within the polymer layer 504, the glass beads 502 can provide a greater tactile feedback to a user when a user touches or moves a finger, fingers, palm, or hand on or over the surface of the glass beaded film 500.

In one embodiment, the glass beads 502 are contiguous within the polymer layer 504 and the exposed top surfaces of the glass beads 502 line up to form a common plane on the surface of the glass beaded film 500. The surfaces of the glass beads can feel to a user like a single continuous surface. When the top surfaces of glass beads form a common plane, the glass beaded film 500 can have a low coefficient of friction that allows a user's finger to move or slide more easily on or over the surface. A user may not feel the individual glass beads when the glass beads 502 are arranged in this manner. In other embodiments, the glass beads 502 are not contiguous and can be in a spaced-apart configuration. Additionally or alternatively, the glass beads 502 may not line up to form a common plane but instead can produce a varied surface on the glass beaded film 500.

In FIG. 6, the glass beads 502 have a high bead sink, meaning the glass beads 502 are positioned at a greater depth in the polymer layer 504 so that a smaller portion of the glass beads 502 protrude from the polymer layer 504. As shown in FIG. 6, the glass beads 502 project out a distance d2 from the surface of the polymer layer 504. The distance d2 is less than the distance d1 in FIG. 5. At a higher bead sink, the glass beads 502 may provide a user with a reduced tactile experience compared to a lower bead sink.

Glass beads having varying diameters are included in the glass beaded film 700 shown in FIG. 7. One size of glass beads 702 having a larger diameter is intermingled with another size of glass beads 704 having a smaller diameter than the diameter of glass beads 702. The different sized glass beads 702, 704 can allow the density of the glass beads in the polymer layer 504 to be greater than when only one size of glass beads are used. The larger and smaller sized glass beads can alternate with respect to each other in the polymer layer 504 in some embodiments. In other embodiments, the glass beads 702, 704 can have any given distribution within the polymer layer 504. Additionally, both sizes of glass beads can be embedded or bonded at appropriate depths so that the top surfaces of the glass beads line up to form a common plane. Alternatively, one size of glass beads can be fixed at a first depth within the polymer layer 504 while the other size of glass beads are fixed at a different second depth, or the glass beads can be fixed at varying depths within the polymer layer 504.

The glass beads can have any suitable diameter or diameters. By way of example only, the glass beads can have a diameter of 5 microns to 100 microns. In some embodiments, the glass beads have a diameter of 50 microns.

Referring now to FIGS. 8-10, there is shown one example method for forming a reduced friction surface over one or more surfaces of a keycap. The illustrated method is a thermoforming method. Although only one keycap and mold is shown, those skilled in the art will recognize that the method can be performed on multiple keycaps at one time.

The keycap 800 is disposed in a lower mold 802 with the glass beaded film 804 overlying the lower mold (FIG. 8). Heat is then applied to the glass beaded film 804 to produce a pliable and conformal glass beaded film. In one embodiment, the glass beaded film is heated to a temperature that is over the film's forming temperature. Next, the upper mold 900 is joined to the lower mold 802 to seal the mold 902 and the air extracted from the upper and lower areas 904, 906 of the mold 902 (FIG. 9). For example, in the illustrated embodiment, the glass beaded film 804 defines upper and lower areas 904, 906 of the mold 902, and the pressure in both the upper and lower areas 904, 906 is zero.

The pressure in the upper area 904 is then increased compared to the lower area 906, which causes the glass beaded film 804 to attach and conform to the keycap 800 (FIG. 10). In the illustrated embodiment, the pressure in the upper area 904 is 60 to 70 kg and the pressure in the lower area 906 is 0 kg. Other embodiments can set the different pressure levels to different values.

The keycap 800 can now be removed from the mold. The glass beaded film 804 attaches to the top surface and all four sides of the keycap in some embodiments, which reduces or eliminates the need to position the transition between the reduced friction surface and the surface of the keycap in a blind or non-visible area.

FIG. 11 is a flowchart of another method for producing a reduced friction surface over at least one surface of a keycap. Initially, one or more glyphs can be formed on a surface of the glass beaded film (block 1100). A glyph can be any character, number, symbol, phrase, or combinations of such elements. By way of example only, a glyph can include a letter or number of a standard QWERTY keyboard. In one embodiment, the glyph is formed on a backside surface of the glass beaded film with a suitable dye or ink. Other embodiments can form the glyph or glyphs on the keycap or on a different surface or location of the glass beaded film.

FIG. 12 depicts block 1100 in FIG. 11. As described earlier, the backside surface 1200 of the glass beaded film 1202 is the side that contacts the surface of the keycap. Example glyphs 1204, 1206, 1208 for three keycaps are shown in the figure. The glyphs can be positioned at any location on the surface. In the illustrated embodiment, the example glyphs 1204, 1206, 1208 are arranged to appear on the top surface of each keycap.

Next, as shown in block 1102, the glass beaded film is heated to produce a pliable and conformal glass beaded film. As described earlier, the glass beaded film can be heated to a temperature that is greater than the forming temperature. The glass beaded film 1200 can be placed on a fixture 1300 that includes openings 1302 (see FIG. 13). The keycaps 1400 are then pressed or pushed downward (as indicated by arrow 1402) into the pliable and conformal glass beaded film 1200, as shown in block 1104 and in FIGS. 14 and 15.

The keycaps 1400 can be mounted on a key fixture 1404 for proper orientation. The pliable and conformal glass beaded film 1200 wraps around and attaches to the top surface of the keycaps all four sides in the illustrated embodiment. The glass beaded film and the keycap form an integrated or consolidated component. FIG. 16 illustrates the keycaps within the glass beaded film 1500. The bottom surface of the keycap may or may not be covered by the glass beaded film.

The key fixture 1404 is then removed and the keycaps 1500 are singulated or separated into individual keycaps (block 1106). For example, a cutting tool can be used to separate the keycaps 1500 along lines 1600 in FIG. 16. FIG. 17 illustrates an individual keycap 1500 after separation. The glyph 1204 (FIG. 12) is visible on the top surface of the keycap 1500.

Referring now to FIG. 18, there is shown a flowchart of another method for producing a reduced friction surface on one or more surfaces of a keycap. Initially, the glass beaded film is formed into a mold having the shape of the surface or surfaces of the keycap the film will overlie (block 1800). FIG. 19 depicts one example of a keycap mold 1900 formed by the glass beaded film. The glass beaded film molds can be produced, for example, using a method similar to the process shown in FIG. 14. In this process, the keycaps are removed from the glass beaded film after the keycaps have been pressed into the glass beaded film.

One or more glyphs can be formed on at least one surface of the glass beaded film mold at block 1802. By way of example only, the one or more glyphs can be provided on the inside surface 1902 (FIG. 19) of the mold. In other embodiments, the glyph or glyphs can be formed on at least one surface of the keycap.

Next, as shown in block 1804, the keycaps can be singulated or separated into individual keycaps. Insert molding is then performed at block 1806 to inject the keycap material into the glass beaded film mold. FIG. 20 illustrates the glass beaded film mold 1900 filled with keycap material 2000.

FIGS. 21-22 illustrate another method for producing a reduced friction surface on one or more surfaces of a keycap. As shown in FIG. 21, a glass beaded film 2100 can include glass beads 2102 embedded or bonded in a polymer layer 2104. An adhesive layer 2106 can be formed over the exposed surfaces of the glass beads 2102. The glass beaded film 2100 can be heated and then pressed down onto at least one surface of a keycap 2108 and the polymer layer 2104 removed (FIG. 22). For example, the polymer layer 2104 can be pulled off when the glass beaded film 2100 is still pliable and conformal, leaving the glass beads 2102 affixed to one or more surfaces of the keycap 2108. Alternatively, the polymer layer 2104 can be peeled off once the glass beads 2102 are affixed to the keycap 2108, regardless of the pliability of the glass beaded film 2100.

FIGS. 23-24 illustrate example keycap shapes. The keycaps can have any given shape, geometry, and/or dimensions. For example, in a QWERTY keyboard the alphanumeric keys typically have one shape and dimensions while other keys, such as the shift and spacebar keys, have different dimensions. The function keys in a computer keyboard can have yet another size and dimensions.

Additionally, one or more surfaces of keycaps can be formed to have varied shapes. For example, the keycap 2300 in FIG. 23 includes a concave top surface 2302 while the keycap 2400 in FIG. 24 has a convex top surface 2204. Other examples of surface features can include beveled, chamfer, rounded, and recessed. One or more techniques described herein can be used to overlay the keycaps with the glass beaded film, despite the shapes, geometries, and/or dimensions of the keycaps.

In some embodiments, the glass beaded film can be a light transmissive film, such as a high transmissive film. The exposed surfaces of the glass beads can be coated with any suitable material to repel contaminants such as dirt, oil, and water. The refractive index of the glass beads can match or substantially match the refractive index of the polymer layer to produce a transparent look. The number of glass beads, the material of the glass beads, and/or the bead sink can be determined based on the surface type, the desired look and feel, the intended use of the electronic device or component in the electronic device, and/or the desired durability of the reduced friction surface.

Various embodiments have been described in detail with particular reference to certain features thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the disclosure. For example, block 1100 or block 1802 are optional and can be omitted in other embodiments. Additionally, as described earlier, the reduced friction surface can be disposed over one or more surfaces of other electronic devices. By way of example only, the surface can be all or some of the enclosure of a tablet computing device, a laptop, and a smart telephone, a button, or another type of input device.

Even though specific embodiments have been described herein, it should be noted that the application is not limited to these embodiments. In particular, any features described with respect to one embodiment may also be used in other embodiments, where compatible. Likewise, the features of the different embodiments may be exchanged, where compatible.
